随着放射治疗的快速发展，对高精度的三维（3D）剂量测量技术的要求比以往任何时候都高。预计3D聚合物凝胶剂量计将满足临床对能够测量复杂3D剂量分布的有效检测器的需求。聚合物凝胶剂量计是利用凝胶中乙烯基单体的辐射诱导聚合反应来存储有关辐射剂量的信息的设备。3D吸收剂量分布可以使用几种成像模式（例如MRI、X射线和光学CT）从所得聚合物分布推导出。本文综述了聚合物凝胶剂量计的基本特性，并提出了在临床推广应用中应注意的问题。
With rapid advances being made in radiotherapy treatment, three-dimensional (3D) dose measurement techniques of great precision are required more than ever before. It is expected that 3D polymer gel dosimeters will satisfy clinical needs for an effective detector that can measure the complex 3D dose distributions. Polymer gel dosimeters are devices that utilize the radiation-induced polymerization reactions of vinyl monomers in a gel to store information about radiation dose. The 3D absorbed dose distribution can be deduced from the resulting polymer distribution using several imaging modalities, such as MRI, X-ray and optical CTs. In this article, the fundamental characteristics of polymer gel dosimeter are reviewed and some challenging keys are also suggested for the widely spread in clinical use.
